Valerie Harper (Valerie Hogan) of "The Hogan Family"

The sitcom began as just 'Valerie,' then 'Valerie's Family: The Hogans,' and ultimately 'The Hogan Family.' In all that repurposing, the series would lose the namesake working mom after two seasons via a car accident and bring on aunt Sandy Duncan to mother the three sons of her sister-in-law. The show would continue another four years.
